RAID 1 (Mirrored Array)

RAID 1 Data Recovery For Hard Drives and SSD
In a RAID 1 configuration, data is duplicated, or”mirrored”, across an even number of drives (RAID is an acronym for a “Redundant Array of Independent Disks”). Many external backup drives, Network Attached Storage (NAS) systems, and desktop systems that contain 2 or more drives will have RAID 1 as a default or configurable option. This configuration will combine the capacity of an even quantity of drives (two, four, etc.) into two mirrored storage volumes. SSD devices are beginning to replace hard drives in many RAID 1 configurations for both commercial and consumer use. Currently, hard drives still comprise the majority of RAID 1 volumes, as they still maintain the advantages of greater storage capability and lower cost.

How Does It Work?
RAID 1 is a storage configuration that allows data to be written to an even multiple of drives at the same time. Many of these volumes will involve just 2 drives, although more can be used in an even numbered pairing quantity. The main benefit to this configuration is data safety. When a data file is being written out, it is “mirrored” or duplicated on more than just a single drive. This configuration can be found in both hardware and software based RAID arrays, and is usually selected when data integrity is the primary concern. RAID 1 can provide quick access to data on the duplicate device in the event of a physical failure of the primary drive.

What Can Go Wrong?
RAID 1 provides “fault tolerance” in the form of data redundancy protection against physical failure. If a one drive fails in a dual-drive RAID 1 array, the second drive can be used as a stand-alone drive to quickly access the volume. However, this configuration is still susceptible to logical problems. For example, file deletions or corruption written to one drive is also duplicated on the mirrored drive. Other problems can occur, which is why it is important that all of the storage devices in the array are evaluated in an “as-failed” state.

When RAID 1 Volumes Fail
VANTEX is your source for professional data recovery for damaged or otherwise inaccessible RAID 1 arrays. We have the tools and procedures in place to quickly and safely recover your data, regardless of the cause. We have decades of recovery experience with file deletions, corruption, viruses and other logical problems within Windows, Linux, Mac, and other operating environments. If data loss is caused by physical or mechanical problems, our dedicated team of recovery specialists can also work to repair, replace or correct problems with heads, firmware, IC components, and other related issues with the drive.
